For milk fat modification, after decantation of its serum, it was fractionated at three temperature rates (30-35, 17-22 and 5-10 ºC) and times (6, 13.5, and 18 hours). After each stage, the solid phase or stearine fraction was separated from liquid phase or olein fraction by centrifugation at 1600 rpm for 15 minutes. The olein fraction was then used in the second step of fractionation. This pro...
In the present study, the transient liquid phase bonding of AISI 2205 dual phase stainless steel with amorphous BNi-3 interlayer was carried out. Based on the initial experimental and analytical studies, the parameters of temperature and bonding time were determined. In order to investigate the effect of bonding temperature on the microstructural changes of the joint, bonding was performed in t...
In this research, effect of nanoparticles dimeter on free convection of aluminum oxide-water was investigated in a cavity by single phase and two phase models. The range of Rayleigh number is considered 105-107 in volume fractions of 0.01 to 0.03 for nanoparticles with various diameters (25, 33, 50 and 100 nm). Given that the two phase nature of nanofluids, necessity of modeling by this method ...
Precise measurement of void coefficient in two phase flow is one of important parameters in thermal hydraulic parameters such as average density, two phase flow pressure drop and two phase flow pattern. In this study the void coefficient has been correlated experimentally based on attenuation coefficient gamma ray emitted form 137Cs source passing a rectangular channel. The average void fractio...
Background: The dispersed phase volume fraction plays key role in oil-in-water emulsion stability by different mechanisms like partial flocculation, depletion flocculation and bridging flocculation. Since the mentioned mechanism is affected by emulsifier concentration presented in system, the major aim of this study was to investigate the effect of dispersed phase volume fraction on physical st...

Structures of two derivatives of the curved fluoradene ring system (C(19)H(12)) have been determined. Both have phases that are highly pseudosymmetric. At room temperature crystals of 7b-triisopropylsilylfluoradene (C(28)H(32)Si) have a P1 cell that contains two independent molecules (Z' = 2) and that is almost centered. Crystals of 7b-(2,4-dinitrophenyl)fluoradene (C(25)H(14)N(2)O(4)) have bot...
chamaemelum nobile (asteraceae) commonly known as 'roman chamomile' is a medicinal plant used for numerous diseases in traditional medicine, although its anticancer activity is unknown. the present study was carried out to investigate the anticancer as well as apoptotic activity of ethyl acetate fraction of c. nobile on different cancerous cell lines. the cells were treated with varyi...
